KENNEDY SPACE CENTER, FLA. -- At Astrotech Space Operations in Titusville, Fla., workers install bolt cutters on one of the THEMIS probes. The cutters will separate each probe from the payload carrier. The probes will undergo weeks of testing and launch preparations. This includes a functional performance test to verify the state of health of each of the five probes and pressurization and leak checks of the reaction control systems. THEMIS consists of five identical probes, the largest number of scientific satellites ever launched into orbit aboard a single rocket. This unique constellation of satellites will resolve the tantalizing mystery of what causes the spectacular sudden brightening of the aurora borealis and aurora australis - the fiery skies over the Earth's northern and southern polar regions. These lights are the visible manifestations of invisible energy releases, called geomagnetic substorms, in near-Earth space. THEMIS will not only seek to answer where and when substorms start, but will also provide clues as to how and why these space storms create havoc on satellites, terrestrial power grids, and communication systems. THEMIS is scheduled to launch Feb. 15 from Cape Canaveral Air Force Station. Photo credit: NASA/Jack Pfaller KSC-06pd2804

CAPE CANAVERAL, Fla. -- After arriving by barge at the U.S. Army Outpost wharf at Port Canaveral in Florida, the second stage, port booster and spacecraft adapter, the remaining stages for the United Launch Alliance Delta IV Heavy boosters for NASA’s upcoming Exploration Flight Test-1, or EFT-1, mission with the Orion spacecraft, were offloaded in their containers. They were transported to the Horizontal Integration Facility, or HIF, at Space Launch Complex 37 on Cape Canaveral Air Force Station. At the HIF, all three booster stages will be processed and checked out before being moved to the nearby launch pad and hoisted into position. The spacecraft adapter will connect Orion to the ULA Delta IV, and also will connect Orion to NASA's new rocket, the Space Launch System, on its first mission in 2017. During the EFT-1 mission, Orion will travel farther into space than any human spacecraft has gone in more than 40 years. The data gathered during the flight will influence design decisions, validate existing computer models and innovative new approaches to space systems development, as well as reduce overall mission risks and costs for later Orion flights. Liftoff of Orion on EFT-1 is planned for fall 2014. Photo credit: NASA/Kim Shiflett KSC-2014-2427
